These pictures show that the regions of the brain used by Deaf people watching sign, and that the hearing
people watching and listening to speech are quite similar, even tho speech and sign are so different.

As previously mentioned, language is a skill that only humans can obtain. A commonly asked
question in regards to humans and language is: What is so special about human brains that lets us understand language?

Luckily, those of us who are deaf can help us find the answer. Since deaf people develop
language skills through speech-reading and sign language, they must make use of the parts of the brain that DO NOT use hearing.

Researchers have also discovered that the auditory cortex (the area that hearing people
use to process sound) can also be used to process sign language by those who use signing as a form of language.

However, for hearing native signers (those born of deaf parents) this area of the brain
is still mainly used for processing sound.
